L3-1/2x3x7/16 (L3.5x3x.4375) – L Shapes - Unequal Leg Angles
L3-1/2x3x7/16 is an unequal-leg angle with 3.5 in (89 mm) x 3 in (76 mm) legs, 7/16 in (11 mm) thick, weighing 9.1 lb/ft (13.5 kg/m).
Unequal leg angles have two legs of different sizes meeting at a right angle, which lets you place the longer leg where the span or connection needs it. They share the practical advantages of all angles: inexpensive, easy to cut, drill, bolt and weld, and useful wherever a structure needs bracing, a connection element or a lightweight framing member. The unequal geometry suits lintels over doors and windows, shelf angles, unequal-leg bracing, truss members and general fabrication work where one direction carries more load than the other.
